PAPER-am)- MAoIIINE.

Application filed September 2, 1924'. semi No. 735,485.

' This invention relates to a paper folding machine for forming a paper board provided with a plurality of folds therein, such a board being illustrated and claimed in a co-pending Patent 1,507,372.

This invention is one form of a machine for forming paper board of the character described, another form of said machine being illustrated and claimed in a co-pending Patent 1,507,373. I

Certain features of the present machine are common to those of the machine before mentioned and are not herein claimed.

The chief object of the invention is to provide. a device for folding. a paper strip or sheet and securing said folds together to form a paper board of the character'indicated.

The chief feature of the invention consists in the simplicity of construction, compact-- ness of arrangement and cert-ainty of operation, whereby a sheet'of paper is creased, pasted and secured together in foldedfr'elas Another feature of the operation several parts'with each other,'wherebysaid parts operate in predetermined timed rela-' tion and in no other relation and, therefore, there is secured certainty o-foperation. r

The full nature of the invention will be understood from the accompanying drawings and the following description and other parts in section, theparts illustrated being shown in the creasing and adhesive applying" positions. v

F 1g. 31s a similar view of the same parts in the folding and adhesive recelvmg position.

Fig. 4 is a similar view of the same parts,

is the associatlon and continuous connection of the showing said parts in an intermediate position.

Inthe drawings 10 indicates a suitable platform or table suitably supported and for a full disclosure of one form of'such support, reference may be had to the before- 'men tioned co-pending machine application. 'ln sultable brackets 11 there is pivotally supported a power shaft 12 which carries a power operable means-such as a pulley 13. The shaft 12 carries an eccentric pin 14 and pivotally supported by said pin and oper- -able thereby is an arm '15. A pair of said arms terminates in a paper shoving or ad vancing plate 16 having the serrated edge 17. W The table 10 is suitably slotted as at 18 and 1s also slotted, substantially across the entire width of "the table as at 19, but there is provided partitions 'orconnect-ing portions 20 which support the paper while passing over the enlarged apertures 19.- The adhesive is applied to the'under side of the paper sheet 21 through said apertures. also is secured therethrough. Pivotally supported beneath the table 10 are a' pair of arms or levers 22. These are creasing pivoted at 23. Each'arm is pivotally connected at 24 to an angular link 25 which is positioned in and extends through the slot 18. 'The opposite, end of'the link 25 is provided with anelongated slot which receives a' pin 27 carried by the actuatingarm '15. The two spaced arms 22 support a casting 28'which' is suitably notched or recessed to clear the supporting partitions 20 of the table thereby permitting the other portions 29 of said casting. to be exposed and project upwardly beyond the level of the support 10 and engage the under side'of the paper'2l, as shown clearly in Fig. 2.

The edge 29 of said casting 28 is adapted to bear upon a supply roller 30, which is rotated in a trough 31 containing a suitable adhesive material 32 which may be of a character such as silicate.

Pivotally supported at 33 is a lever 3 f having an extension 35 with which is associated spring 36 for returning said lever into is provided with an elongated slot 37, in which rides a pin 88 carried by the arm or lever 22. hen the arm or lever 22 is tilted upon its pivot 23, said tilting movement causes the pin 38 to ride in the slot 37 of the lever 34 and tilt said lever 3st. Two spaced levers carry a creasingplate 89, suitably recessed so as to clear the longitudinal supporting partitions 20 of the table 10.

- raciall *sspperiea"upen:611e, or-if desired, upon each ofthe anns 2sandat40 is a detent 41 which is adapted to. engage a ratchet wheel 42 concentric with tlie"roller 30 and to rotate saidrollerin the tank 31 containing the silicate A spring 4:3 -Iioruially niaintainssaid detent in ratchet engagement. Thus, as shown clearly in Fig-3,

upon. the forward throw of, the actuating arm 15, link positively tilts the lever 22 to cause the adhesive sup-portingsurtace 29.. .to-be supplied with adhesive. from roll 30.

Simultaneousl i with said movement detent elrotat'es rate iet 42 which rotates the adhesive supplying roller 30 120 deposit adhesive upon the portion. 29.

Inthis forward movement of the foregoing parts the platelb carries forward the strip ot'paper :21 at a greater rate than it has heretofore been moving and at a greater rate than the preceding portion is moving,

' so that it tucks the following portion of the paper under the preceding portion of the paper to form a told. This told, as shown clearly in Fig. 3, includes the adhesive coverect-portions so that there is no; adhesive. exposed upon either of the exposed surfaces of; said; folded sheet.- when folded. Upon'the return niovementofthe arm 15 and substantially at the endlof-said; movement the surface 29 containing the adhesive engages the paper. sheetflland; applies adhesive thereto see Fig.2.. Upon theinitial return movement ofrthe' arm '15; the plate 16 causes the paper tobe creased by reason of the engagement. of the paper covered'plate, 16 upon the creasing member 89. movement tilts the: creasing member 39 out oi engagement with thev paper portion pre viousjly creased and th s position 13 shown in iontinuec advancing movement of the actuating arms 15 with "folding plate 16com- I pletes the paper foldcovering the adhesive applied portions thereof and simultaneously deposits additional adhesive upon the adhesive applying member 29. v I

Pivotally supported. abovethetable atthe portion where the creasing and adhesive applying and toldingoperat-ions take place is a thefoldedpaper and tends to maintain the.

pivotally supported plate. 50 that bears. upon plying means.

Continued forward whereby the creasing and folding is accom- 'plished. r

The invention claimed is:

1. In a paper board machine, the combination "with paper creasing means, paper applying "folding means and adhesive means, of means for positively actuating the adhesive applying means in timed relation with the paper foldingmeans; and means connecting the adhesive applyingmeans and the paper creasing means 'for acti iating the atter by the former in timedjrelation' therewith and with the 'pap'e'r'folding means.

2 i-ii. device as defined" byfclaiin 1, charac- .te-rized. by the actuating ii'i'eanscincluding a pin and slot cont-inous connection between the paper 'folding'means and; the adhesive applying means, and the connecting means iiicludinga pinland' sl'ot continous connection between the adhesive applying means and the paper creasing means for securing predetermined movements therebe'tween and the means connected through the adhesive ap- 3. A device as defined by claim 1, characterized by the adhesive applyingmeans including a vpi otally.mountedadhesive applying plate.
